and made discoveries that will form large contributions to 

 geological knowledge of Labrador. Among the many 

 special subjects which he investigated were the following:* 



(i) Phenomena of former submergence and subsequent 

 uplift of the coast. This has occurred since the glacial 

 epoch, and not to the same extent on different parts of the 

 coast. There is a maximum of uplift in the vicinity of Hope- 

 dale (390 feet), whence its amount diminishes steadily toward 

 the north, being 250 feet at Nachvak, and toward the south 

 to a minimum about Hamilton Inlet (260 feet). From the 

 latter it again increases southw^ard to another maximum in 

 Newfoundland, attaining 575 feet at St. John's. The de- 

 termination of these facts has involved: 



First, a study of raised beaches and other elevated re- 

 sults of the former contact of land and sea. The heights 

 of a great many of these were measured, and an attempt to 

 correlate them led to the opinion that they were not formed 

 at corresponding heights in the different localities by rela- 

 tively long pauses in the process of uplift, as has been sur- 

 mised; but that their particular heights are due to local con-, 

 ditions of exposure and rock-resistance, and need not cor- 

 respond in height in the different localities. 



Second, the discovery of a criterion for determining the 

 upper limit of former submergence. This was found in the 

 boundary between the boulder-strewn upper and the 

 boulder-free low^er zone, the former having evidently never 



* This outline was given to me by Dr. Daly immediately after our 

 return from Labrador, and is subject to any corrections that may appear 

 in his own account of his results. These have now been given in his

 of Comparative Zoology at Harvard College, Vol. XXXVIH, February,
